"And that all sounds I suppose a little bit restricted, but the point is I think within the Avatar landscape I can say everything I need to say that I think needs to be said, in terms of the state of the world and what I think we need to be doing about it," he stated.

It was recently reported that Cameron could shoot the Avatar sequels in China.
